Dirks accompanied the Mud Hens on the road to Columbus, where they'll play five games in four days against the Clippers.
The Tigers haven't announced a timetable on Dirks' stint, other than manager Jim Leyland saying it won't be a quick one. He missed about two months with what was expected to be a day-to-day Achilles injury, so he has time to make up.
Whenever he does come back, the Tigers have a decision to make on how to make room. With Omar Infante taking over at second base, Ryan Raburn is now an extra outfielder with Don Kelly. Kelly, like Dirks, bats left-handed. Neither can be optioned to the minors, essentially, given Raburn's right to block an assignment.
